kavy0:
may I tell
yes you can please tell me
See if in the outer most she'll of an atom contains 1,2,3,4 then it is a metal. If an atom contain 5,6,7,8 electrons then it is a non metal
when an atom has one two three or four electrons in its outermost shell it is a metal it means that it can donate these items while when an atom has five six seven eight electrons in its outermost shell it is a non-metal which means that it has to accept electrons
please mark me brainliest
we both are right about this answer
know if it has eight electrons in its outermost shell then it is a noble gas
you are wrong
there must not be 8
except 8
